Youhavedownloaded.com exposes the download habits of BitTorrent users, The developers of the site want to make people aware of the public nature of BitTorrent, and are currently working on a more anonymous version of the leading file-sharing technology.

YouHaveDownloaded is a new Russian-based service that claims to track about 20 percent of all public BitTorrent downloads. However, they go a step further than just collecting IP-addresses and file-names by exposing all the harvested information to the public on their website.

People who visit the site immediately see their download history, as far as it’s available in the site’s database. In addition, they can also search for files or IP-addresses to find out who’s downloading what. At the time of writing the database has information on 51,274,000 users who together shared 103,200 torrents.

TorrentFreak got in touch with Suren Ter, one of the site’s founders, to find out why they decided to create this spying tool.

“We just want to remind people that the Internet is not a place to expect privacy,” he says. “Nowadays many people use it without understanding what information they leave behind. Also, even those who understand choose to ignore it quite often.”

The Russian developers created the site partly as a wake-up call. Those who don’t want this kind of information to be public should take steps to anonymize their traffic, and do that right. This message is also reflected in the site’s ‘privacy policy‘.

“Baby, this is the Internet. There is no such thing as privacy around here. You are sitting in the privacy of your own house, clicking links, reading stuff, watching movies. It may seem like you are pretty much alone, but smart nerds are watching you. They watch your every move. You are not human to them. You are a target — a consumer,” it reads.

Jokes aside, the site does indeed make people aware of the public nature of BitTorrent, something that can’t be stressed enough. Of course not everyone will be happy to see that their information is being exposed, so the developers also offer an option to de-list an IP-address.

Apart from exposing download habits the developers are also considering the creation of a more private file-sharing protocol. They already have a theoretical concept based on Bitcoin’s technology, but a workable piece of software is still very far away.

“The general idea is similar to what Bitcoin does. The key is to have an anonymous and reliable identity for each peer, and a Bitcoin-like signature chain algorithm will help,” Suren said.

The developers are currently trying to find out how viable their idea is, and then they’ll decide whether they should continue working on it or not. For now, they’ll keep on tracking dozens of millions of downloaders, for all the world to see.

Update: For those who have dynamic IP-addresses the service is obviously going to show content that someone else has downloaded.
